To compare phosphorus intake and renal phosphorus regulation between thermally injured patients and multiple trauma patients, 40 consecutive critically ill patients, 20 with thermal injury and 20 with multiple trauma, who required enteral tube feeding were evaluated. Phosphorus intakes were recorded for 14 days from the initiation of tube feeding which was started 1 to 3 days postinjury. Serum ...

BACKGROUND AND OBJECTIVES Disorders of mineral metabolism are more common in African Americans with CKD than in European Americans with CKD. Previous studies have focused on the differences in mineral metabolism by self-reported race, making it difficult to delineate the importance of environmental compared with biologic factors. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS In a cross-sectio...

Improvement of phosphorus circulation in the soil is necessary to enhance phosphorus availability to plants. Phosphorus circulation activity is an index of soil's ability to supply soluble phosphorus from organic phosphorus in the soil solution. To understand the relationship among phosphorus circulation activity; bacterial biomass; pH; and Fe, Al, and Ca concentrations (described as mineral co...

Problem statement: There is evidence that the type of fiber influences the development of nephrocalcinosis in rats, but the effect of pectin was unknown. Approach: The effects of dietary pectin and cellulose on kidney calcification were studied in female rats. The diets used contained either 0.4-0.6% phosphorus and either cellulose (10%, w/w) or pectin. The purified diets used were balanced for...

Restoring historic lake-fringe wetlands is considered a favorable means of reducing lake phosphorus levels; however, it is unclear how various strategies for managing wetland connectivity influence phosphorus release. We investigated the relationships between temperature and soil characteristics of restored wetlands to identify management strategies that minimize external phosphorus loading to ...

A new fertilizer technology developed at Penn State University offers several potential benefits for turfgrass cultivation. The new technology employs a phosphorus buffering system (PBS), which , maintains a steady phosphorus concentration in the soil solution over time. The PBS has the size and consistency of sand (Fig. 1) and can be mixed with any soil media. Once charged with phosphorus, the...

abstract plant species differ in their ability to grow at low available p soils in other words, plant species differ in p use efficiency at low p supply. this ability can be investigated by comparing p uptake efficiency of plants and relative effective factors. a pot experiment was carried out in the growth chamber and sugar beet, maize and groundnut were grown in a low available p soil in a co...

native phosphate solubilizing bacteria (psb) were isolated from four areas (ankober, keyt, mehalmeda and molale) of ethiopia to study their effect on releases of soluble phosphorus from insoluble p sources. the highest bacterial number was found at keyt (2.6103 g-1soil) and the least at molale (15 g-1soil). five efficient psb were selected for further study based on their ability in forming a ...

Because previous studies have demonstrated that renal inorganic phosphate reabsorption is enhanced in rats after dietary phosphorus deprivation, we studied the effects of parathyroid hormone (PTH) upon inorganic phosphate reabsorption in acutely thyroparathyroidectomized rats stabilized on a low phosphorus diet to determine if the phosphaturic response to PTH is impaired during phosphorous depl...

BACKGROUND External nutrient discharges have caused eutrophication in many estuaries and coastal seas such as the Baltic Sea. The sedimented nutrients can affect bacterial communities which, in turn, are widely believed to contribute to release of nutrients such as phosphorus from the sediment. METHODS We investigated relationships between bacterial communities and chemical forms of phosphoru...
